Seroprevalence and risk factors associated with Neospora caninum in crossbred dairy cows in Uberlândia
Neospora caninum causes reproductive disorders in dairy cattle such as repeat breeding, abortion, and anestrus, which are risk factors associated with the seroprevalence of N. caninum in Brazil and worldwide. This study aimed to verify the risk factors related to the seroprevalence of Neospora canin...

| description | Neospora caninum causes reproductive disorders in dairy cattle such as repeat breeding, abortion, and anestrus, which are risk factors associated with the seroprevalence of N. caninum in Brazil and worldwide. This study aimed to verify the risk factors related to the seroprevalence of Neospora caninum in crossbred dairy cows in the city of Uberlândia, Minas Gerais. During, January to July 2013, 740 blood samples were collected from 57 herds with a history of reproductive disorders and determinations of antibody titers against N. caninum were obtained by ELISA assay. The seroprevalence of N. caninum was 18.4% (136/740). Risk factors for N. caninum were cows greater than 2 years of age (P = 0.034), mechanical milking (P = 0.012), and frequent purchase of animals (P = 0.004), in addition to individual history of abortion (P = 0.007) and repeat breeding (P = 0.030). The highest probability of occurrence of associated risk factors was associated with individual history of abortion and repeated breeding and the frequent purchase of animals, with odds of 12.8, 5.9, and 3.8 times, respectively. In conclusion, the risk factors associated with N. caninum: members of the female sex and cows with more than 2 years-of-age, mechanical milking, and the frequent purchase of animals, in addition to individual history of abortion and repeated breeding. |
